“I actually have the ES900m, which doesn't have microphone and control buttons, but the rest is the same.
For $6 it's impossible to buy a pair of earphones as good as them. I really believe that the body of the earphones are metal, even if they are not, it's made of a very durable plastic. It's nothing like the entry-level Sony or Philips earphones which are made of cheap...” --mrplt

“The ES800 are the kind of IEMs you won't like how they sound out of the box: they sound thin and aggressive, with piercing mids and highs.

Build quality: the Q9s look nice and they sure are big. So big that I doubt anyone with small ears will be able to insert...” --Mellowship

“
What can I say about these? I saw a lot of people going for the Awei branded items on eBay, so I got one myself. They were surprisingly good and surprisingly bad at the same time. I will explain.
Pros
Housing build - For $2, an aluminum housing is quite exceptional.
Accessories - While the Awei K80 only comes with one pair of tips, they are surprisingly pretty high quality. Somewhat...” --pro1137
